Great headphones!!! The sound is pretty good, not bulky at all, just perfect. I own PPC 6700, which does not have A2DP, in order to control wirelessly the windows media player. I did some research , and downloaded a software from the internet, and that way I got the headphones working. Just google it A2DP for PPC 6700 and you will find it too.
It is worth it!

If you are like me, you have struggled with headphone wires your entire life. I would envy those in the gym jamming out to their favorite tunes and I would wish I could bare the wires which always seemed to get tangled in a machine or snag on cables.
I purchased this pair of headphones and have been nothing but impressed and utterly satisfied. The price is $90 less than BestBuy sells it for and it works every bit as well. You can run with these and they do not move or bounce on your ears. They are sweat proof, I have a tendency to work out with a vigorous intensity and I perspire quite a bit, these hold up nicely.
I do not mind the flashing lights, in fact, when running or jogging at night it's a great secondary safety measure to save you from being struck down by an automobile or by deer.
If you are debating between this pair and the motorolla set, stop what you're doing and purchase these. The Fit and Finish, the quality of the product and the sound quality are far and away superior to the Motorolla set which I had to return 3 times.

At first, I didn't know if I should purchase this product. I had seen pictures of people wearing them (looked nerdy), I have heard complaints of the sound, and I have heard complaints of the battery. I decided to just take the plung. After I charged the battery, synced it to my ipod (via bluetooth accessory), and started playing music, I was totally blown away! Ya, they look a bit geeky looking and if you let the blue lights blink, you look like a cross between princess leah and r2d2 but hey! The sound is the most important part and the sound is simply amazing! How's the battery, you ask? Way better than I had expected. I have played movies and music on my ipod, I have hooked them up to my laptop, and I have yet to charge it and the first charge was a week and a half ago!!!!! How are they comfort wise? sometimes it puts a pinch on my right ear a bit if I wear them too long but I think that is because I wear glasses. Oh, and if you are a ps3 fan, these headphones are awesome to use. especialy in home when you want to talk to your friends at your house. This is great for many different things and guess what. you can connect to two things at once, so if you are gaming and get a call from your cell, you can swap in a flash to your cell. what more can you ask for?
